CZ DUTY 4.0 F MS
About this product
Quick order is the whole idea here, and a factory pistol fits that idea better than anything. CZ's new DUTY 4.0 is one listing, four versions, no jig, no frame-fitting, no parts list to check. It is a striker-fired 9x19mm service pistol with the serial number on an internal chassis, a modular fiberglass-reinforced polymer grip frame, a direct-mount optics cut on the slide and fixed iron sights.
Read the model code and you know the gun. C is the compact, 15+1 or 17+1 with the extended base plate, 770 g and 135 mm tall. F is the full-size, 17+1 or 19+1 extended, 780 g and 143 mm tall. Add MS and a manual thumb safety joins the firing pin block, trigger safety and trigger bar safety. All four share a 4-inch unthreaded barrel, 7.4-inch overall length, 1.3-inch width and a refined SFDA trigger at about 5.6 lbs with a 4 mm reset. List price is $729 MSRP.
Under the DUTY name sits a serialized modular chassis, a 1.3 in (33 mm) wide fiberglass-reinforced polymer frame, a four-inch barrel and a trigger CZ rates at 25 ± 4 N (5.6 ± 0.9 lbs) with a 0.16 in (4 mm) reset. The slide is optics-ready by direct mount rather than an adapter plate. Fixed sights come standard, and the barrel is not threaded.
This is the longer grip of the two DUTY frames. It holds 17+1 rounds, 19+1 with the extended plate, stands 5.6 in (143 mm) and weighs 27.7 oz (780 g) unloaded. Same slide, same four-inch barrel as the compact, so the sight radius is identical; you buy the F for the grip and the extra rounds.
This is the version with a manual thumb safety. The three internal safeties (firing pin block, trigger safety, drawbar safety) are the same as on every DUTY; the lever is an extra for people who were trained on one or simply want one.
Best fit: home defense, duty use, competition and long range sessions where the extra grip and two more rounds matter. Shooters coming from a CZ 75 will recognize the grip angle; owners coming from any other striker gun will notice the trigger first.
Quick order still means one extra step for a complete firearm: a dealer. Enter your FFL's details when you order and the DUTY 4.0 ships to them, not to you. Pickup happens at the dealer, who applies the rules your state sets for handgun transfers. Frames, jigs and parts in the same cart go to your door as they always have.
